Subject: Can a PC talk to a TTY?
I have a pc clone and a 300/1200/2400 baud modem. I was wondering if it
is possible to talk to the type of teletype device used by deaf people.
If so, are there any programs around to do this and/or what are the
protocols?
I called Bell Canada's Centre for Special Needs, but they were no help at
all.
Thanks in advance,

Subject: Re: TSR for periodic execution of a function
The question comes from Alessandro Russo Morten Welinder and
<NIJKERK%HROEUR5.BITNET@CUNYVM.CUNY.EDU> provided helpful information but
I want to point a few things:
The 1Ch is executed by the Int 8 which normally is the hardware timer
tick. The timer tick interrupt has the highest priority.
You don't need to include CLI as the first command of your 1Ch handler
since this is done automatically by the CPU.
THERE IS NO WAY for an 1Ch to occur while processing the previous one
except if you send an EOI (End Of Interrupt) to the PIC (Priority
Interrupt Controller), and of course enable the interrupts.
While processing your 1Ch interrupt the CPU denies any other interrupt
(even keyboard interrupts). As you can understand there is no reason for
a flag-byte to signal whether we are in the 1Ch handler or not. Things do
get complicated if you want keyboard access while processing the
interrupt. You have to send an EOI to the PIC and this time you NEED a
flag to signal an 'already processing' condition.
Your interrupt handler should complete the job very fast. The Int 8
executes 18.2 times/second, that is, a timer tick interrupt occurs (..and
an 1Ch interrupt) every 0.0549 secs Your handler should do the job in less
than 0.0549 secs else you'll have problems like incorrect time.
If your 1Ch handler crashes then Ctrl-Alt-Del will not work (why ?)
Finally you could chain directly to the OLDINT1C handler when your handler
ends (e.g. JMP FAR OLDINT1C) instead of calling the old handler using a
PUSHF, CALL (...) combination.
If you have any questions just drop a note.
Stanley Fragakis, Greece (CSSTU011 at GRCRUN11)
PS: Can you answer this? Why it is not necessary (most cases)
to save the AX register in your 1Ch handler?
Answer to me directly.

Subject: Reminder Programs
I really like Ample Notice. I have version 1.07. I just checked a list
of Simtel-20 files, and saw AN108.ARC in PD1:<MSDOS.DESKACCESS>; I assume
it is version 1.08.
Ample Notice understands concepts like 2nd Sunday in May (Mother's Day),
2nd Wednesday of every month, July 4th, etc. I (at least) think it is
easy to use.

As a first guess, I'd say you have a somewhat noisy AC line and the
occasional glitches are interfering with the keyboard register. I used
to have that problem along with a few others; a major investment in a
line voltage regulator fixed that OK. A cheaper alternative might be
effective, one that provides spike or surge arresting.

Subject: Kermit Source
The source for all Kermit programs is available from Columbia University.
You can either use ftp to logon anonymously to CU20B, or use KERMSRV at
CUVMA (a BITNET LISTSERV machine). I recommend looking at MSKERM.DOC
first. It not only describes how to use MS-Kermit, but lists special
versions (p. 3), and describes organization (and names) of the source
files (p. 83). Have you tried version 2.32? It first checks whether the
serial port is standard; if so, it sends commands directly to the port;
otherwise, it uses BIOS. It works on my DG/One, although the combination
of BIOS calls and a slow machine results in loss of characters at
connection speeds above 300 bps. If the machine you are trying to use is
a DG/One, please let me know; I would definitely like a version of Kermit
tailored for a DG.

Subject: pc/ix on at&t 6300
Ref: Need assistance with PC/IX.
AT&T 6300 is supposed to compatible... (V20 is upwards compatible with
8088). However PC/IX does not use BIOS and has its own drivers for all
devices. It supports only 17 sectors/track hard disks and if you have
PC/IX 1.0 not even all of those. THe hard disk is the most likely
cause of your troubles. If your disk is a 17 sectors/track then get
PC/IX 1.1.

There are a number of question regarding just what are the bugs in PC-DOS
4.00. IBM does supply a fix-disk to upgrade PC-DOS 4.00 to 4.01. On
these disks (three in all) there is a README document that lists these
bugs. This is that README file:

Subject: Toshiba 1.44MB Disk Question (Resolved)
Thanks to all who responded re: whether the Toshiba 3.5" 1.44MB floppy
drive detects HD disks and acts accordingly. The answer is apparently yes
(at least in combination with Zenith's MS-DOS 3.3+).
I had the HD cutout drilled out of a 720K floppy drive, and the Toshiba
now recognizes it as a HD diskette (before I did that, the drive would not
read a 720K diskette formatted as 1.44MB on another machine). Covering
the slot with a piece of tape yields abort, retry, fail, ignore?
attempting to read the disk as a 1.44MB.
Again, thanks to all who responded; I hope this helps someone else.

Subject: Turbo Clone Mode
I have an AT Turbo (VIP-200) which can run at 6Mhz or 13Mhz. The high
speed is switchable either from a front panel switch, or the key sequence
"Ctrl-Alt-\". The key sequence acts as a toggle.
I have reason to want to switch the turbo mode under program control. It
would seem to me that if the key sequence would do it, and key sequences
are in the Phoenix BIOS (3.11.00 I think), then I could replicate it with
a program.
I have tried debugging the BIOS for the various keyboard interrupts. Does
anyone know how I could toggle the speed with a program?
As a side, it would also be nice to be able to tell at which speed the
computer is operating, but that is secondary.
Thanks,
Steven Christensen

From: "James H. Foggin" <PA44908%UTKVM1.BITNET@CORNELLC.CCS.CORNELL.EDU>.
A few months back I purchased a typewriter which I also wanted to use as a
printer. I wanted full word processing capabilities when used as a stand
alone typewriter as well as letter quality printing when connected to a
computer.
I purchased a Panasonic RKX-350. The computer interface module was
separate. The total cost was about $300 ($250 + $50). The interface
module connects to the PC's parallel port. I have only used it a few
times as a printer for MS Word, but I am satisfied with its performance.
The main shortcoming is that the plastic film typewriter ribbons are not
cheap, cannot be reused, and don't last very long (a few thousand
characters). Cloth ribbons are available, but the print quality is not as
sharp as with a plastic film ribbon (although still acceptable). The good
part about the ribbon is that the less expensive Brother typewriter
ribbons can be used instead.
Another bad point is that the daisy wheel is available only from Panasonic
and costs about $20, but fortunately it has a long lifetime.

See the pd1:<msdos.worldmap> directory on Simtel20 for a world map
database. However, it may not be what you're looking for if you wanted
political boundaries (state lines), or cities, or topography. You should
have been a little more specific as to what type of map you wanted.
